Kirk, You are correct. I was able to run some samples in the old jar files using 64 bit java and they work. At the time I thought there was a problem with it, I think I was trying to run the MvsConsoleInteraction class, but it works now. I was trying to invoke MvsConsoleInteraction from a 64 bit program, instead of running it directly. Maybe that caused an error which I thought was because it was supposed to be run only from a 31 bit program. I ended up writing my own DLL to put out the console messages so at least I learned something from my mistake.
Anyway, thanks to everyone for their input. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Kirk Wolf Sent: Friday, January 11, 2019 2:38 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Do I need to copy a mainframe flat file to OMVS, before I access the data from a JAVA program? - JZOS question Eileen, The JZOS sample (Java) code consists of samples that use the JZOS API that is part of the SDK. There would not be any code in these that would be dependent on the bit width of the SDK/JVM. Also, the file listing that you show above are the source files. It appears to me that they all have the date that the zip file was built (unfortunately). I can assure you that these dates don't represent the last time that the source file was changed. You can prove this to yourself by diffing the two zip files that you have. Take for example the ZipDatasets.java example that you mentioned. I don't see any changes except for some minor javadoc cleanups since I originally wrote it 10 years ago.
